When you're not using the bag turn it upside down o the bottom will tan.. in time you wont see those.
All,
Here are the stains I'm talking about. And when I received the bag, the leather was "virginal white." I tried to be careful when sitting it down yesterday, but I guess I missed one area in the seat next to me. Anyway, here are the stains. Will they eventually be covered as the leather darkens?
